A ball, like liquids, travels downwards. So, when you blow on it, you give a push to the ball. When the ball loses the power, it rolls downwards. (Out the pipe)

When you put a ping pong ball in a funnel and blow in the funnel why does the ping pong ball stay in it?

The reason the ping pong ball stays in the funnel when you blow in it is because of Bernoulli's Principle. This principle states that as the speed of a moving fluid (liquid or gas) increases, the pressure within the fluid decreases. When you blow in the funnel at a high speed, the pressure around the ball decreases. Then, the pressure from the outside of the funnel (because there is air pressure everywhere) pushes down on the ball at a lower speed, which would mean higher pressure, which causes the ball to stay inside the funnel. Mind you that the bernoulli's principle is based in the wind tunnel or venturri tube and the funnel is an example of a venturri tube, so that would further explain it.

How does blowing air through a funnel pick up a ping-pong ball?

I think you're referring to the funnel apparatus where the large end of the funnel is pointed down. The funnel itself is just a little larger than the ping-pong ball. Air is blown through the funnel downward towards the ping-pong ball, but the ball doesn't drop. Instead it is held fast inside the funnel. The explanation lies with the Bernoulli Principle. This principle states that along any streamline of air (a streamline is the path that an air molecule takes), if the velocity of the air drops then the static pressure at that point will rise, and vice-versa. So what happens with the funnel and ping-pong ball is that the air coming out of the funnel has to flow around the ball and therefore it becomes constricted against the sides of the funnel. It doesn't have much room to get by, in other words. That means it has to flow faster over the top of the ball. Faster = lower pressure. When it gets by the ball and expands in the funnel, it slows down. Slower = higher pressure. This pressure difference (high pressure below, low pressure above) is what keeps the ball suspended in the funnel.
